AC Gnd DC input coupling switch on 466

Edward Prest

The ch 2 lever moves but stays in dc mode. There is no detent snap but some drag going through gnd position.

Am I correct assuming this is a loose grub screw?

Edward Prest

Yes, one loose, the other channel ready to let go. Both tightened.
It took 4.5 hours to pull the boards and put it all back.
